Abstract：The search angle is an imporment factor to be considered to improve the prodiction distance and accuracy in the gedogical prodiction with TSP-202 seismic system. With the theory and method of probability，tectonic geology and material mechanics，the search angle obtained by TSP-202 seismic system is analysed. An adjustment method is proposed for the search angle to improve the prediction accuraey，and applied in Xinluona tunnel with good result.
